Detailed explanation-1: -Exocytosis is the opposite of the processes discussed in the last section in that its purpose is to expel material from the cell into the extracellular fluid. Waste material is enveloped in a membrane and fuses with the interior of the plasma membrane.

Detailed explanation-2: -Exocytosis is the process by which vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the cell’s external environment. This is the form of transport used by a cell to dispose of large molecules.

Detailed explanation-3: -Exocytosis is the process by which cells move materials from within the cell into the extracellular fluid. Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Detailed explanation-4: -During exocytosis cells expel a variety of materials including waste products, toxins and large molecules such as hormones, proteins and neurotransmitters into the extracellular environment.

Detailed explanation-5: -Exocytosis is a form of bulk transport during which large numbers of molecules are transported out of the cell. In exocytosis, a vesicle (a small, membrane-bound compartment) containing the molecules to be released fuses with the cell membrane, and the contents of the vesicle are expelled.
